The cut is from a r32 i always thought it was a vin number change and thats it. Iv jump the gun and put race seats and gave it the jdm drift look as thats what the car is for and a daily car. Just hope i dont have to take it back to stock.

nup

it used to be a headf**k. front brakes had to be changed to R32 GTSt, and engineer's certificate required.

Now due to regency accepting the fact that a 20DET is a 31 direct bolt-in they've now classed it as that. Basically u fill in the "application to modify a vehicle" form and submit the change in engine numbers. if they ask if you have done any brake upgrades, tell them so. Usually they'll look happily at just upgrading to slotted rotors and better pads for the front.

But do ring and check

Hmmm wudnt mind putting one in my 32, if i had the money to do so, but id want to do the whole lot. Gearbox, diff, and engine. But then some custom work would be needed for the tailshaft which could get messy. Guess i gotta give my the boys down at regency a call.

      R34 GTT idle problem

      Not really, no. Anything you would do is easily reversible.

      Mistakes were made, my R34 Story

      I would like more noise related info for my truly uneducated guess  Does it do it at idle or when revving, clutch engaged, and disengaged? Does it only do it when the car is moving? I've heard "similar" noises from a clutch pack that left the chat room, and CV joints that have chewed themselves out But as Matt said, how's the yokes, tailshaft and centre bearing going after their last little issue Fingers crossed it is something simple  Weird noises make me cringe

      One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.

      Pfft. As if I'd ever point a high pressure washer at my car.

      R34 GTT idle problem

      By GTSBoy · Posted

      The nature of my commute has changed. Way back then it was traffic lights all the way, for ~28km. It sucked. When they finally stitched the expressway together I could do a good 15+km of it at a steady 80-100 with no stopping. That alone has gotten me down to flat 10s. Prior to that it was mid-high 10s. I can't remember the delta that I saw when I got the idle down. It was only ~150 rpm, because the idle speed was never terrible, but for the delta in consumption to be noticeable it would have had to have been at least 0.2-0.3 L/100km - which is not to be sneezed at when it comes for absolute free. It's only about 50L per year, but that's ~$100. A few extra pizzas is always welcome. Note that I have a record of every tank of fuel that has ever gone through my car except for a handful put in by someone else, like my mechanic. I can show you the difference between stock RB20 and tuned RB20, stock RB5Neo and tuned, winter and summer fuel blends, winter and summer fuel blends when the ambient temperature is not appropriate for the blend, working O2 sensor, blown O2 sensor, boosting f**k out of it and frightened to boost it because it is pinging, and so on. OK, I probably can't do all that now with 100% clarity - but at the time when any of those things were in event, you could see it in the records. There's 25+ years of simple tank after tank records, so you have to look for landmarks to work out approximately how old any single record is. What's really important is the meta data and that lives in my head.
